 /**
  * Service interface with public versions of the protected
  * <code>java.net.URLStreamHandler</code> methods.
  * <p>
  * The important differences between this interface and the
  * <code>URLStreamHandler</code> class are that the <code>setURL</code> method is
  * absent and the <code>parseURL</code> method takes a
  * {@link URLStreamHandlerSetter} object as the first argument. Classes
  * implementing this interface must call the <code>setURL</code> method on the
  * <code>URLStreamHandlerSetter</code> object received in the <code>parseURL</code>
  * method instead of <code>URLStreamHandler.setURL</code> to avoid a
  * <code>SecurityException</code>.
  *
  * @see AbstractURLStreamHandlerService
